Description:

This error code, VLC 002050.09, indicates that the Vehicle Load Center (VLC) control unit has detected that the Cab Load Center (CLC) control unit’s Controller Area Network (CAN) message is missing. This suggests a communication failure between the VLC and CLC control units.

Reaction:

When this fault is detected, the VLC may not receive necessary operational data from the CLC, potentially leading to malfunction or improper functioning of various vehicle systems controlled by the CLC.

Recommendations:

Inspect CAN Bus Connections:

• Verify that all CAN bus connections between the VLC and CLC control units are secure, free from corrosion, and undamaged. Repair or replace any faulty wiring or connectors.

Check CAN Bus Termination:

• Ensure that the CAN bus is properly terminated at both ends with the correct termination resistors. Incorrect termination can lead to communication failures.

Verify Power Supply:

• Check that both the VLC and CLC control units are receiving a stable power supply. Fluctuations or interruptions can cause communication issues.

Update Firmware and Software:

• Ensure that the firmware and software for both the VLC and CLC control units are up-to-date. Update as necessary to resolve potential compatibility issues.

Consult Technical Support:

• If the issue persists, contact technical support for further diagnostics and assistance. Provide detailed information about the fault and the steps taken to resolve it.

Note:

CAN bus communication issues can be caused by factors such as electrical interference, damaged wiring, or incorrect network configurations. Regular maintenance and inspection of the CAN bus network can help prevent these issues.
